Jamie Foxx is in final negotiations to star opposite Gerard Butler in "Law Abiding Citizen," a psychological thriller that Frank Darabont is directing for the Film Department.

Written by Kurt Wimmer and Darabont, the script follows a successful assistant D.A. (Butler) who finds himself at the center of a vigilante plot hatched by a traumatized victim of the legal system (Foxx). Foxx's character is devastated to learn that, because of a plea bargain, one of his wife and daughter's murderers will be set free. So he unleashes revenge on the killers and those who made the deal.

Butler and his Evil Twin shingle partner Alan Siegel are producing along with Warp Films' Lucas Foster. Film Department's Mark Gill also is producing.

Executive producing are Film Department's Robert Katz and Neil Sacker.

Foxx, repped by CAA and King Management, next stars opposite Robert Downey Jr. in "The Soloist," directed by Joe Wright ("Atonement").
